Morris Arboretum isn't the only public garden in the region offering outdoor music events this summer, and I hope to get to some of these, as well. They're at Swarthmore College's Scott Arboretum, which has a stupendous outdoor amphitheater, and at Longwood Gardens, too.
Both are lovely venues for musical performances, and you can get there early and wander the grounds. For a nice summary - a summery summary - go to:
